A Modified Version of the Transactional Stress Concept According to Lazarus and Folkman Was Confirmed in a Psychosomatic Inpatient Sample.

Background: Stress is a major risk factor for the impairment of psychological well-being. The present study aimed to evaluate the empirical evidence of the Transactional Stress Model proposed by Lazarus and Folkman in patients with psychosomatic health conditions.

Methods: A structural equation model was applied in two separate subsamples of inpatients from the Department of Psychosomatic Medicine (total = 2,216) for consecutive model building (sample 1, = 1,129) and confirmatory analyses (sample 2, = 1,087) using self-reported health status information about perceived stress, personal resources, coping mechanisms, stress response, and psychological well-being.

Applying Item Response Theory to the OPD Structure Questionnaire: Identification of a Unidimensional Core Construct and Feasibility of Computer Adaptive Testing.

Recent developments in the dimensional assessment of personality functioning have made the implementation of latent measurement models increasingly attractive. In this study, we applied item response theory (IRT) to a well-established personality functioning instrument (the OPD Structure Questionnaire) to identify a unidimensional latent trait and to evaluate the feasibility of computer adaptive testing (CAT). We hypothesized that the use of IRT could reduce the test burden - compared to a fixed short form - while maintaining high precision over a wide range of the latent trait.

A Step Towards a Better Understanding of Pain Phenotypes: Latent Class Analysis in Chronic Pain Patients Receiving Multimodal Inpatient Treatment.

Purpose: The number of non-responders to treatment among patients with chronic pain (CP) is high, although intensive multimodal treatment is broadly accessible. One reason is the large variability in manifestations of CP. To facilitate the development of tailored treatment approaches, phenotypes of CP must be identified.

[Empirical Assessment of Patient-Reported Outcomes and Exemplary Introduction to Health-Related Quality of Life].

Health-related quality of life (HRQoL) acquires increased importance as a target parameter for different stakeholders in healthcare, e. g. to assess treatment outcome in chronically ill patients.

A 67-item stress resilience item bank showing high content validity was developed in a psychosomatic sample.

Objectives: To develop the first item bank to measure stress resilience (SR) in clinical populations.

Study Design And Setting: Qualitative item development resulted in an initial pool of 131 items covering a broad theoretical SR concept. These items were tested in n = 521 patients at a psychosomatic outpatient clinic.

[Evaluation of Factor Structure and Construct Validity of the 12-Item Short Version of the OPD Structure Questionnaire (OPD-SQS) in Psychosomatic Patients].

Background: Screening for personality dysfunction is regarded as increasingly important for treatment planning in clinical settings as this allows to determine specific clinical pathways in an early stage. Recently, the 12-item OPD Structure Questionnaire (OPD-SQS) was developed for this purpose and initial results of the factor structure and validity have been published. This study aimed to investigate and validate the OPD-SQS in further patient samples beyond the team of developers and to provide reference values.
